Information About Fabric Binding

The fabric binding feature ensures that ISLs are only enabled between specified switches in the fabric. Fabric
binding is configured on a per-VSAN basis.
This feature helps prevent unauthorized switches from joining the fabric or disrupting current fabric operations.
It uses the Exchange Fabric Membership Data (EFMD) protocol to ensure that the list of authorized switches
is identical in all switches in the fabric.

Licensing Requirements for Fabric Binding

Fabric Binding requires the Storage Protocol Services license.
